This is a really well designed, quality feeling drive (aluminium enclosure) combine with the Toshiba brand name at this point it sets it apart fom the competition. I paid £99.99 a few weeks back and i'm very happy with it.

Choose the capacity that better fits your needs: the Toshiba STOR.E ALU 2 external hard drives have a compact and pleasant design, it is pre-programmed with a security software, low power consumption feature, this drive has got everything. Add extra storage with Toshiba. In a stylish design, Toshiba USB 2.0 External Hard Drives are the perfect storage solution for your digital videos, photos and music files. The 3.5" USB hard drives may be used in a horizontal, or vertical orientation on your desktop. These high speed hard drives, ranging from 160GB to 1TB, provide excellent performance, and with their fanless design, are near-silent in operation. Connecting via USB, they are a great way to backup your files for future recovery, or as a storage solution for large media files such as HD video.

Any external HD with a USB 2.0 or FireWire Port (presuming that your Mac has a corresponding port) will work with your Mac. There is no difference between hard drive technology for Macs and PC's - they both use the same.

You can expect a lot of these and other USB2 HDD Drives going a lot cheaper as the on-line shops get rid of them as USB3 enters the market big time early next year. Think I'll wait but voted hot as it's the cheapest I've seen.
